This is almost correct but a few things should be pointed out.  The
original 520ST had an RF modulator, but the disk drives were external.
Later versions (and the 1040ST) had a built in floppy drive.  To 
differentiate the 520's, the name was changed to 520STFM, where the
F meant builtin floppy drive and the M meant RF Modulator.  The 1040ST's
had a built-in floppy, but not an RF modulator.  I don't think they were
called 1040STF's though, since they all came that way until the 
1040STe's came out which do have an RF modulator.  Some of this is from
memory and what I have read.  I have never had an ocassion to have one
of each vintage sitting in front of me to confirm this.  :-)
